This inventionrelates to improvements in concrete structures. 4 V

The general ob ect of this invention is to provide an improved means for securing 5 devices to concrete structures.

Another obj set of this invention is to provide an improved article securing insert for concrete constructions. y

A further object of the invention is to provide an improved insert for concreteconstructions wherein a staple is used to secure devices to the insert.

Other objects and the advantages of this invention will be apparent fromthe follow- 15 ingdescription taken inconnection with the accompanying drawing wherein Fig. 1 is a fragmentary side View of a concrete post partly in Section, embodying the features of my invention; f q i Fig. 2 is a front face viewof my improved insert showing it operatively positioned in a concrete post. H

Fig. 3 is a view similar to Fig. 1 showing a staple about to be driven intocthe insert.

Fig. 4 is a-fragmentary,view ofaconcrete post mould form-with-one side removed to show a manner of positioning theinserts in the mould. i r v Fig. 5 is a central section through a modified form of insert showing it 'operatively positioned in, a concrete base-and Fig. 6 is asection of a building wallshowing another use for my invention.

Referring to the drawings by reference characters I have indicated my improved insert generally at 10 and have shown it in connection with a concrete post 12.

' Although I show and describe my improved insert in connection with a concrete post it will be understood that it may be used, with equal success, in other forms of concrete construction. i

As shown, my improved insert 10 comprises a metal cup member it having tapered side walls anda bottom wall 16 adjacent the center of which is provided an aperture 17. r

A sheet metal cap19 having a reduced and the flange 20 is adapted to engage the flange 20 is provided on the cup member 14 inner faces of the side walls 15 as shown. The cup 19 is preferably of less diameter than the diameter of theoutside of the side walls 15 sothat when the cap is positioned on the cup member considerable space is left on the ends of the side walls 15,: as indicated at 21.

The reduced flange 20 of the cap 19 is preferably of slightlygreater diameter than the diameter of the inner faces ofthe side walls 15 so that it is compressed when inserted in an operative position and tightly engages the inner faces of the side walls 15, thereby preventing the cap from becoming displaced when the cementis poured over it.

' The cap may be otherwise secured in place if desired.

In Fig. 41 have shown one manner inv which the 'insert 'lO may be positioned in'a mould for forming concrete posts. As shown the inserts 10 are placed on the bottom member of the mould and dowels 26 secured to the bottom member project through the'apertures 17 of the inserts, holding the inserts in' the correct position while the cement is being poured inthe mould.

In the accompanying drawings I have shown a strand of fence wire 28 secured to the post 12 by a staple 29 which is clinched to the insert 10.

The staple29 is an ordinary wood staple of a size wherein the diameter of eachprong is about half. the diameter of theaperture 17 The staple is first positioned over the wire 20 and then the prongs of the staple are bent together by a pair of pliers or any other to the ends of the side walls 15 andas the s majority of the surface of the ends contacts with the cement as indicated at 21 the strain is taken up by the cement and the sheet metal cap 19 is not injured, also the abutting of the ends of the side walls against the concrete prevents the cup member from being driven into the concrete.

In Fig. 5 I have indicated a modified form of insert generally at 30. This insert is similar to the insert and comprises a metal cup shaped member 31 having tapered side walls 32 and a bottom wall 33 adjacent the center of which is provided an'aperture 34. A sheet metal cap 35 is provided on the cup shaped member 31 of the insert 30. This cap comprises a reduced flange 36 adapted to engage the inner faces of the side walls 32 and is divided into a plurality of segments 37. An outwardly turned flange 38 is provided on the segments 37 which are adapted to be positioned in a groove 39 on the inner face of the side walls 32 when the cap is operatively positioned on the cup shaped member 31, as clearly shown in Fig. 5. ,When the cap 35 is being positioned on the cup shaped member the segments 37 contract and allow the flanges 38 on the segments to enter the cup shaped member and then the segments expand again as the flanges enter the groove 39, thus securely holding the cap to the cup shaped member.

A staple is used to fasten elements to the insert 30 in the same manner as previously described in connection with the insert 10.

In Fig. 6 I have shown the method in which my improved inserts may be used for supporting reinforcement for concrete to which veneer tile are frozen. In this view I have shown the insert 10 as cast in a con- Crete wall 40 and having a staple 41 clinched thereto which is adapted to support a strand of reinforcing wire 42 which is embedded in a layer of concrete. The veneer tile 43 are placed against the concrete or cement where they freeze or adhere.

having a hollow portion and including a part substantially parallel with the face of the wall and a portion imbedded in the wall, said part having an aperture therein communicating with the hollow portion, a reinforcing member adjacent said wall, a looped fastening member engaging said reinforcing member and passing through said aperture and having the ends crossed within the hollow portion whereby said portion 7 islocked within said insert, said fastening member and said ca than the outside diameter of said side wall of the cup shaped member and said ca including a side wall having a reduced ange thereon, said reduced flange being positioned within said side wall of said cup shaped member, said flange being in resilient engagement with the inner face of said side wall.

3. In a device of the class described, a cup shaped member including a side wall and a bottom wall, said side wall being tapered outwardly from said bottom wall, an aperture in said bottom wall, a cap, said cap being less in diameter than the outside diameter of said side wall of said cup shaped including a side wall having a reduced ange thereon, said reduced flange being divided into a plurality of resilient segments, an outwardly projecting portion on each of said segments, a groove in the inner side wall of said cup shaped member, said outwardly projectin portions on said, segments being positioned in said groove when said cap is operatively positioned on said cup shaped member.

4. For use in a concrete construction, an insert including a hollow member having an aperture therein, said aperture being of less diameter than the interior of said member, a staple inserted in said a erture, said staple bein made of wire an the ends of said stapIe being divergent within said hollow member, said aperture having a diameter which is reater than twice the diameter of the wire fiom which the staple is made, said aperture also having a diameter which is less than the distance across the outside of the staple loop.

In testimony whereof, I hereunto aflix my signature.
